You "enter" the draft if you are an undergraduate. If you have used up your eligibility, you don't enter the draft. But, the WNBA doesn't permit anyone to be drafted who hasn't completed their four years.
Maybe you just did a quick synopsis and I am confused. Epiphany Price is an example of someone who left school before completing four years, played overseas a year and came back and was drafted. She was eligible after playing pro for one year overseas thus renouncing i.e. her college eligibility (though she could have just renounced her eligibility and waited a year without going overseas) AND that after the year overseas the class she would have graduated with was graduating that spring. There was a time when I could just break this down quickly but has been awhile since I have been engaged in the topic, so I will just post the NCAA memorandum. Also, please note that these requirements do not apply to players from other countries. I have addressed the international players. Not completely sure the international is correct as the link was from 2009, but I believe it is.
[I realize this may too much info for some but thought I would provide this in case anyone was interested. It also helped me to do a little research as I had become foggy on these rules. I have followed the WNBA off and on since 1999 so when something comes up that I have forgotten, I have to go digging for answers.]
Who is eligible for the WNBA Draft?
Per WNBA eligibility requirements the following individuals are eligible:
a. An individual who will be at least
22 years old during the calendar year in which
such draft is held and she either has no remaining intercollegiate eligibility or
renounces her remaining intercollegiate eligibility by written notice to the WNBA at
least 10 days prior to such draft; SO here 22 in relevant, she does not have to attended college
b. An individual who has graduated from a four-year college or university prior to such
draft, or "is to graduate" from such college or university within the three-month
period following such draft and she either has no remaining intercollegiate eligibility
or renounces her remaining intercollegiate eligibility by written notice to the WNBA
at least 10 days prior to such draft; or
SO here graduation or is to GRADUATE within 3 months after draft is pertinent
c. An individual who has attended a four-year college or university, her original class in
such college or university has already been graduated or "is to graduate" within the
three-month period following such draft, and she either has no remaining
intercollegiate eligibility or renounces her remaining intercollegiate eligibility by
written notice to the WNBA at least 10 days prior to such draft.
Here it is about having attended a 4 year university and her original class has graduated or is to graduate within the 3 month period following the draft
d. An individual who is competing in an NCAA season (including any NCAA
tournament) during the period that begins 10 days prior to the draft; has remaining
eligibility beyond the season in which she is currently competing; and is otherwise
eligible for selection in such draft, may make herself eligible for such draft by
renouncing her remaining intercollegiate eligibility within the period beginning at the
conclusion of her final NCAA game in the season in which she is currently
competing and ending 24 hours thereafter (but no later than three hours prior to the
draft).
Main thing is addresses playing during 10 days prior to draft so an exception to the 10 day period to THREE HOURS prior to draft
INTERNATIONAL PLAYERS: an international player is eligible to
be selected in the WNBA Draft if she will be at least 20 years old during the calendar year in
which such Draft is held.
(e) For purposes of this Section 1, an “international player” means any person
born and residing outside the United States who participates in the game of basketball as an
amateur or a professional.
(please note: I believe this is still true I could not find current rules)
Also, if
an international player plays intercollegiate basketball in the U.S. then the rule is: attended a fouryear
college or university, her original class in such college or university has already been
graduated or “is to graduate” within the three (3)-month period following such Draft, and she
either has no remaining intercollegiate eligibility or renounces her remaining intercollegiate
eligibility by written notice to the WNBA at least ten (10) days prior to such Draft. S
o again about her original class graduating
SORRY, if this seems obnoxious. I know anyone could have looked this up but I looked it up and put it here for those interested.
